    Obviously, it's true what you say, it's just base on Hardware Defines Stuff.

    We use a lot of software define storage SDS, or software defines networking, and with that, we can easily without many efforts push SoftHA to everybody.

    Not for the customer, but for us especially.
    If we maintain an HDD or just OS patch/update (we use LivePatch from January, so no need reboot now) take time and sometimes customer need to use their app on that time.

    Some customers just want high SLA, just because the wrong maintenance or failure will make them lose a lot of money, and this is not seen as annual SLA, but maybe monthly, having just 5 min of downtime is really hard to offer without some kind of HA.

    It's completely true that good hardware can reduce a lot of inconveniences, and in most cases, it will protect the customer really well. But now that we have SDS and is easy to manage and really robust, we can move to that and countless on hardware.

    Obviously, there are 2 ways Hardware and Software and there are pros and cons for both, I just see Cloudron as more oriented on Software than hardware, and to replay the main question of this post, I think that softHA base on SDS can be easily implemented compared to some of the super costly hardware by DELL or HPE and provide scalability other than a soft approach to HA.

    But I support your thesis to, good hardware is absolutely a good way to provide good SLA.

      Mostly Ceph, if is not needed an other stack by the customer.
      But I have tested recently the new ScaleOutZFS by truenas scale, and it's really good and easy to manage, but is not a really 100% SDS.

          Not that I remember, but I'm not actually the CTO, so in some cases i just know of the production / future production ready solution that we are testing or using.
          I don't keep up with all the project that we test or try.

              Hey everyone, hope it's ok if I chime in here and ask if anyone has built something in this direction. I'm asking because I got approached to host a static site (basically html, js and a few smaller images) which has trafficspikes where 50k+ users will try to access it for a short period of time and then mostly idles again. How would you go about that, is this doable on Cloudron? I did manage to have 100s of users, but 1000s is a different story 😬

              Can the surfer app (being a node server and all) handle that load if there's enough CPU/RAM on the host machine? Or would you rather build a custom nginx app which does nothing but serve compressed static files? Or fire up some smaller VPS, install nginx and use a load balancer to spread the traffic? Any information and suggestion is appreciated 🙂

                @msbt I actually think for your scenario with mostly static content, you could put Cloudflare or similar in front of that app to sustain those spike times.

                  For static content, this should be quite easily achievable. Have you tried running any load tests? There's a bunch of variables here like network and disk speed. Best to measure the actual server setup.

                    thanks for the replies 🙂

                    @nebulon I wanted to avoid Cloudflare traffic, but I reckon it's worth a try

                    @girish I'll do some local and remote http benching as soon as I have an idea what the actual content of the site will be

                      If you're simply against Cloudflare as some people seem to be but open to other CDNs, I can vouch for BunnyCDN, everyone raves about them and they are very inexpensive too for the offerings. They also seem to be about to launch some DNS packages, I think they're slowly taking direct aim at Cloudflare and seem a little more friendly to use.

                        @d19dotca funny that you mention them, BunnyCDN was the provider I wanted to check out before any other 😄

                          Moving to a K8s is hard for sure, simple things get more complex. But I think that's the best long term and where I see things going at large. Maybe setting it up as a single-node k8s would be easier initially?

                          If Cloudrun was set up to run as a single or multi-node Kubernetes (k3s/rke) cluster it opens the door to tons of cool stuff. You could for example use Rancher/Fleet to manage all your Cloudron/K8s migrations, monitoring, security, etc.

                          I use Rancher/k8s for multi-node / multi-cluster stuff and Cloudron for single system. Rancher connecting to a k8s version of Cloudrun would be the pie in the sky for me.

                            "Lens for the web browser - coming soon" Currently is a desktop app...

                            Lens is also open source and the "free" tier seems like it would fit a majority of Cloudron's users use cases...k0s is free/open source too where as Lens does have a "Pro" version for teams and is only $19.99 a month per user but is not "necessary"
